Abstract
Proposed is a locking differential drive, in which, between a first side of a differential cage (3) and a cover (4) a crown wheel (2) is located, which is turnably connected with the cover (4) and the differential cage (3), and the radial extent of which crown wheel (2) is less than that of the opening (9) of the differential cage (3), which said opening serves for the installation of differential bevel gears (10, 11). The crown wheel (2) exhibits two contact faces, of which a first contact face (7) serves as a seat for a clutch (6) of an externally lockable differential drive and a second contact face (8) serves as a seat for a clutch (17) of a self-actuating lockable differential drive. In this way, the same crown wheel (2) and the same differential cage (3) can be employed both for an externally lockable differential drive as well as a self actuating differential drive.
